Companies delay earnings due to hurricane

Drugmaker Pfizer Inc. and power companies Entergy Corp. and NRG Energy Inc. said they would postpone releasing quarterly earnings results because of the hurricane approaching the U.S. Northeast.

Pfizer and Entergy had been due to report their third-quarter results on Tuesday. NRG was scheduled to release its results on Wednesday.

Pfizer rescheduled the release of its results and its conference call with analysts until Thursday, November 1, citing "the expected severe weather conditions associated with Hurricane Sandy."

Entergy pushed its conference call back to November 5. It said it was making the move in consideration of those preparing for the storm.

NRG rescheduled its third-quarter earnings call until November 2.

Other companies, such as energy company Anadarko Corp., are going forward with their earnings releases as planned. Anadarko will announce its results on Monday afternoon, according to a company spokesman.

NYSE's closure of its physical trading floor operations on Monday is the first in nearly three decades due to a weather-related emergency.
